[Cons Himself]

We need a concerted effort to gather together all the known FACTS from all five games so far in the Half Life Universe:

Half Life
Half Life: Opposing Force
Half Life: Blue Shift
Half Life: Decay (from the PS2 version)

Half Life 2

What I mean by this is all snippets of plot relevant conversation, all Gman sightings, plot relevant events that are both audio, visual or implied.

A good place to start would be with the manuals. I know for a fact that the original Half Life and Half Life: Opposing Force had plot relevant parts to their manuals: Gordon's letter and Shepherd's Diary.
Im not sure about Blue Shift or Decay, but hopefully someone can shed light on them. I know for a fact that Half Life 2 has no manual so never mind on that front.

So a good place to start would be scans of the manuals if anyone has them!

Thanks!
